Avoid image copy in toTexture() on GLES 3.0 as well

The default backingstore implementation is now cleaned for ES_2 ifdefs.
All the checks are now done at runtime and ES 3.0+ is included as well
for the efficient, QImage::copy()-less path.

For embedded a customized backingstore is used so the change has to be
done separately there.

This should result in a slight improvement for QOpenGLWidget/QQuickWidget
when running on GLES 3.x.
